The invention discloses an experiment table feedback adjusting system for a fuel cell. The system mainly comprises a hydrogen tank, an air bottle, the fuel cell, a measuring instrument, a data acquiring and processing system and the like. The invention also discloses a working method of the system. Certain single parameter of inflow gas of the fuel cell is changed, the performance of the fuel cell is tested multiple times under the condition that other parameters are kept unchanged, and accordingly, optimal working parameters of a tested fuel cell stack are obtained. By means of the experiment table feedback adjusting system for the fuel cell and the working method of the experiment table feedback adjusting system, the change of the single parameter of the fuel cell can be tested, the performance parameters of the fuel cell under the condition that certain single variable is changed are measured safely and stably, and accordingly, the performance of the tested fuel cell is understood more comprehensively. Moreover, only water is produced after the test reaction, no pollutants are contained, and zero discharge of the pollutants is realized.
Description
technical field [0001] The invention belongs to the technical field of fuel cells, and in particular relates to a fuel cell test bench feedback adjustment system and a working method thereof. Background technique [0002] A fuel cell is an electrochemical energy converter that converts chemical energy in fuel directly into direct current. The fuel cell uses hydrogen and air as fuel, and generates water after the reaction, which is non-polluting and recyclable. It does not go through the heat engine process, so it is not limited by the Carnot cycle, and the energy conversion efficiency is high (40%-60%). Fuel cells can be ideally all solid state mechanical structures, the system has high reliability and long life, and since there are no moving parts, the fuel cells are very quiet. Because of the above advantages, fuel cells can be used as a substitute for internal combustion engines in automobiles, and can also be used in small-scale centralized power supply or decentralize...
